Prometheus raises a $12B Series B at a $41B valuation for AI tools that design physical products

Prometheus, the company Jeff Bezos leads as co-CEO with Vik Bajaj, announced a $12 billion Series B that values it at about $41 billion, according to CNBC. It launched in November 2025 with $6.2 billion. Bezos said he took part in the round; the company has shared few details about its other backers. He told CNBC that Prometheus has "nothing to do with robotics" and is developing an artificial general engineer: "We're building tools that will make it much easier for engineers to design physical objects." He described the system as a "very, very modern version" of CAD and said it was premature to give much detail. The company works from San Francisco, London and Zurich.
